Note from Penny: When I have children here I tell them that Tangs are like "ocean cows" & I ask them what cows eat. Grass! they shout! Yes! So if these fish are like cows, what do you think is the food they should eat? They look puzzled & that's when I pull out the Nori & tell them SEAWEED!! They laugh & say Yes! Tangs are by far one of the most popular of all the Reef Fish categories! Click on the individual Tangs below & inside I'll tell you more about the "personality" of that fish & how to be successful with them ... like I am. :c)
